There is a large difference between targeting "who you want" and "who you can effectively cater to".
It costs a metric fuckload of dollars to penetrate a market (in this case skiing), and compared to their snowboarding market, were probably not getting a huge amount of growth out of their brand. Some higher ups had to tell Anon to downsize, and naturally they're going to have to take out the business unit that's making the least amount of profit. I'm sure Anon would LOVE to be a widely respected brand in skiing and would love to have a wide and expansive team, but as it is skiers view Anon as a snowboard brand trying to be skiing, and that's probably why they never really cut into the sales of Oakley, Smith, or Scott and eventually had to pull out of the market leading to threads like this.But don't be confused thinking that Anon is just abandoning skiing
because of a few individuals (some might argue that, ahem) or because
they don't like skiing. Burton is a well run business, and ultimately
the decision probably came down to Anon not making enough money to be
competitive in the skiing market.
Brand positioning also plays into it a lot I'm assuming, but that's an entirely different point altogether.
But to reply to your post more specifically, as a consumer (and as a human being) you have complete free reign to do whatever the fuck you want, and personally I'd rather see skiing-specific brands grow than other sports trying to cut into this market. So boycott? I don't know if one should go to that extreme, but ultimately you're going to make purchases based on your values, wants, and a handful of other factors, so do what you want and what you're most comfortable with.
